Fourier Math.NET Numerics Documentation Packed Real plex forward Fast Fourier Transform (FFT) to arbitrary length sample vectors. Since for real valued time samples the complex spectrum is conjugate even (symmetry), the spectrum can be fully reconstructed form the positive frequencies only (first half). Math.NET Numerics Math.NET Numerics, providing methods and algorithms for numerical computations in science, engineering and every day use. .Net 4, .Net 3.5, SL5, Win8, WP8, PCL 47 and ... Math.NET Math.NET. Math.NET is an opensource initiative to build and maintain toolkits covering fundamental mathematics, targetting advanced but also every day needs of .Net developers. How to interpret these FFT results? Signal Processing ... Note the symmetry in your 3rd plot. That tells me the MathNet.Numerics FFT is computing a full frequency FFT (both positive and negative frequencies), and plotting the FFT results where zero Hz should be the center of the horizontal axis. However, Problem# 1, for some reason the labeling of the horizontal axis does NOT have zero Hz in the center. Numerics FFT result interpretation Math.NET Numerics ... You actually have two peaks of the same magnitude, one at index 100 and one at index 900, hence 200 Hz (100 * 2 Hz). This is expected since for real valued signals the FT will be real even and imagniary odd, so there is a symmetry between positive and negative frequencies. FFT of Large Data Math.NET Numerics Math.NET About sample size and the FFT, figure out the largest sample size that is convenient and practical. There isn’t too much to gain by going to a huge number because there is a limit on what you can display on a monitor which is, say, 2000 pixels across.

C#によるWaveデータのFFT処理 | TomoSoft Visual Studio Express 2013を使用し、C#言語によりWaveファイル形式でWaveデータに対して、FFT処理を行います。FFTの計算には、Math.NET Numericsを使用します。1722Hzと861Hzを加算したデータ長100msの正弦波に対して、FFT処理を行います。 parison of FFT Implementations for .NET CodeProject I was particularly interested in 1D FFTs for real valued input (audio processing). The following interface is used for all tests. If you have your own FFT implementation, it should be easy to incorporate it into the benchmark by implementing this interface and instantiate the test in the Util Math.NET Filtering Math.NET Filtering, providing methods and algorithms for signal processing and filtering in science, engineering and every day use.
